OpenCV, Processing, Windows Vista = Blank window

edited March 2015 in Library Questions

Hi all

I am trying to run some of the OpenCV examples in Processing, but am getting the infamous black screen. I have no problem getting video feed from the webcam in the video examples, but with the OpenCV examples, such as face detection and blobs, I have had no luck.

In the tutorial I started with, it was recommended to download OpenCV 1 (, so that's what I tried. I am doing this on an old Windows Vista computer and running the latest Processing, 2.2.1

I searched for solutions and tried this with no luck: . Steps needed to solve problem: Install Quicktime 7 Install a vdig driver: Run Processing in compatibility mode for windows xp sp 3 . More searching, and still no luck on a solution that works.

In one discussion, I saw a link to the processing forum, but the post seems to be gone:

Anyway, if you could please help, or steer me in the right direction, it would save me from going any further insane!

    Nevermind, turns out there is only one OpenCV version, and one OpenCV library (the gab.opencv) that seem to work with Windows Vista.
